In today’s quick tip, let me offer 5 Networking “buzz words” you should know:
- Get VPN – Group Encrypted Transport – Developed by Cisco in 2006 to allow secure connections over the Internet which is very easy to implement and maintain.
- GDOI – Group Domain of Interpretation – Provide a “key” to decrypt or encrypt your data – related to ISAKMP – see RFC3547 for more information.
- MTU – Maximum Transmission Unit – In relation to IP, it sets an upper packet size limit for maximum packets.
- ICMP – Internet Control Message Protocol – Messages that are contained within IP packets such as 0 for Echo Reply or 5 for Redirect. ICMP could be called the network managment protocol for IP.
- WCCP – Web Cache Communication Protocol – WCCP is a protocol for communication between routers and Web caches. Two versions exist: WCCP Version 1 (WCCPv1) and WCCP Version2 (WCCPv2). The two versions are incompatible. Cisco IOS images can support either of the two versions or both.
